chromatography system or peristaltic pump and

condition it as instructed below:

1. Set pump flow rate to 3.0 ml/min (731 cm/hr)

for the 1 ml cartridge or 6.0 ml/min (288 cm/hr)

for the 5 ml cartridge.

2. Wash the cartridge with degassed low-salt

buffer for 2 min.

3. Wash the cartridge with degassed high-salt
